    May 16, 2020· Gold cyanidation, also called cyanide leaching, is a process used toextract gold from raw ore taken from the ground. It uses cyanide to dissolve the gold within the rock, which, itself, is not soluble in cyanide. The gold is then drawn out in a liquid form that can be treated to remove the cyanide.
